The Observations and Measurements (ISO 19156) observedProperty may be a reference to any type. A useful model is the SWE Phenomenon from SWE Common 1.0
The observedProperty may describe the  geophysical or biophysical measurements available in the product. E.g. Sea Surface Heights, Significant Wave Heights. Ozone concentration, NDVI
Multiple properties may be described by the SWE CompoundPhenomenon</documentation>
